Supplementary Material

For more information of the generation of the results for the routing path R, as discussed in the preliminaries in section 2, readers are referred to the online supplementary material for details. Each column on the excel worksheet represent one of the highest survival probability for rescue operations, in a form of matrices and vectors representing deployment locations, connection, routing, fault tolerance, etc., before the final survival vector αR is generated. This αR is iterated 6 times (where 6 is the total number of iterations) taking into consideration the rock hardness cases β (Table 2). All the 6 cases are considered in the final survival vectors R. This R in equation (13) is the final survival probability vector which is used as the input to the neural network training as shown in Figure 1.
